can`t you use Lime? garden lime for instance, that`s Calcium Oxide, so is the granular stuff in the botton of those ready heat cans of coffee (you know the sort, press a button at the bottom and shake and wait for a few mins).

it`ll "Slake" the lime making Calcium Hydroxide, then you can re-distil it

it can react with the ethanol if memory serves, long before you add the alu, besides, even if I`m wrong about the C2H5Na, that reaction would still only split the Hydrogen off the OH leaving sodium aluminate and just as much water as you started off with. (either that or I`m having a "Blonde moment")

possibly Cement, although it will be quite messy and hard to clean afterwards, it Should ignore the alc and use only the water, I`m also sure that PolyAcrylAmide will work too, you`ll not need to distill it afterwards either

if you distil Ethanol that contains water, no mater how perfectly you control the temp, you`ll still only ever get a 98% pure product, even though water boils at 100c, it will form an azeotrope with the alc, bummer I know, but it`s a fact

Yeah, I know that, that's why I was talking about the using chems to removed the water.

bezen works but only once.

Thanks for letting me know what the word ment, yeah its 95% for ethanol/water.

yeah, some sitting outside my front door in the flats smoking and tinfoil and graffiti pens all over the floor and some on mt front door (WD-$) removed it) and I "removed" them too slow/stoned to hit me back, but it doesn`t stop my wife and newborn child getting upset

anyway, that`s off topic.

you Might be interested in the polyacrylamide crystals though

you can also buy them at B&Q used for adding to the soil in hanging baskets as a water reserve, they absorb upto 400x their weight in water!!!! amazing I know

O cool. I was trying find what that stuff was.

Yeah thats great stuff, but does it react with ethanol, i take it as a no.

There was some guy whos made some 'stuff' just like that but it works alot better, somewhere around the 2000x mark.

He made it to absorb clouds to stop hurricanes in yanky land.

worked so fast, bowl of water and just a tea spoon, pow all turned into gel.

ok , in order, I`ve tried the gell in Vodka and it worked, HOWEVER it was only 40% alc to start with, so maybe it takes longer or needs to finer powder and constant agitation to absorb all the 5% water? OR... maybe the C2H5OH molecule is too big and blocks the "pores" in the gell? (I honestly have no idea why it didn`t work).

the copper sulphate, you`ll need to make it also into a powder and heat it until it goes nearly pure white and anhydrous, again, I can`t vouch for that as a valid and workable solution it may just suffer the same prob as the gell?

Actually, the anhydrous copper sulfate isn't that bad of an idea since the water molecules are chemically and physically trapped into the crystal structure of the salt. Same can be said for the cobalt compounds that absorb water. The only problem is that you don't want any of that Co remaining in your ethanol.
